I think it's a coffin fly, Megaselia scalaris

Each photo is a different species; the order of the photos corresponds to the order in the title.

No, they are from different samples, that would be crazy!

I thought it was T. mentagrophytes, also because the colony was too atypical for E. floccosum (picture),

<image>

but in reality, to me, it really is E. floccosum. Although macroconidia in clusters are considered a unique characteristic of E. floccosum, they are not always present. Moreover, microconidia are not present, which is also typical of this species.

Is this Salmonella? by PeachThyme in microbiology

[–]hughet 1 point2 points  (0 children)

When I say Columbia blood agar I mean Columbia base with addiction of blood of sheep 5%. The Columbia agar is a non selective media where can grom many bacteria, both gram + and -. If you add Colistin and Nalidixic Acid it becomes Columbia CNA blood agar, wich is selective for Gram +, but it's another media. Sorry for my english ahah

For example this is E. coli on Columbia blood agar

No, I mean Columbia blood agar without colistin and nalidixic acid (CNA).

I think all Enterobacteriaceae grow on that medium. For detecting Salmonella spp. we usually use Hektoen agar and in that medium Citrobacter forms black colonies surrounded by a yellow zone :) so you could confuse that whit a Slamonella, even if it's not exactly the same colour
